United States Marine Corps Campaign Advertisement Essay

The campaign advertisement ran by the United States Marine Corps uses versatile imagery and a connotative language approach to strategically attract minority women. The print ad shows a female Marine in a defensive martial arts pose on looked by a crowd of men in what seems to be a combat training session implying she is the leader. The tag line: â€Å"There are no female Marines. Only Marines† suggests that women who join the Marines will have equal standing with men in their organization. The ad itself appears to be in a military instructional setting. The viewer’s eye is immediately drawn to the central focus of the document; a strong, physically fit African American woman in a combat stance, facilitating the techniques of martial arts.†¦show more content†¦The objective appeal is that the advertisers would like you to enlist in the Marine Corps. To a generation of women who have become used to the â€Å"glass ceiling†, or have become complacent with making seventy-five cent on the dollar as compared to their male counterparts, the simple visual of the strong empowered female who has a group of men at her command can be very compelling. Similarly, in our current recession, formatting of the word into a â€Å"Want† ad is a very strong pull. This appears to be a viable solution for unemployed women, minorities, and recent high school graduates seeking employment in a market that is not very receptive right now. This is not a job, it a career, a lifestyle, this woman is in command and you can be too. The strategies employed in this ad and the emotions this advertisement speaks volumes about the company that produced it. The military has always been something of a â€Å"man’s world†, where men were on the front lines, and running the show, and if a female were present she would be seen in a nurses unif orm. This ad is a public statement by the Marines into equalization of the sexes, and a huge leap into the present societal mindset that women are in fact, able to do anything men are. It is a modernization of an established military branch. This ad shows that the US Marine Corps recognizes their traditional enlistment strategies did not appeal to women. More importantly, demonstrating willingness to revise theirShow MoreRelatedEssay on Adding to the Advertisements1383 Words   |  6 Pagesthe German people to their side of the struggle to great effect (Hitler).

Annotated Bibliography On Cryptography And Presence Of...

Cryptography The practice and study in securing communication between parties in presence of potential adversaries. A cryptographic algorithm or cipher is a mathematical function used in a plaintext in the encryption and decryption process. A cryptographic algorithm works in combination with a key (number, word, or phrase) to encrypt the plaintext. The same plaintext also encrypts to different cipher text with the use of different keys. The core of modern cryptography is the construction and analyzation of protocols of various aspects in information security such as data integrity and confidentiality, authentication, and non-repudiation. Modern practice of cryptography involves cryptographic method. First cryptographic method is the Symmetric-Key Algorithm also known as Secret key Cryptography. The symmetry of algorithm comes from both parties involved sharing the same key for both data encryption and decryption. It works like a physical door where anyone who has the right locking and unlocking uses a copy of the same key. Symmetric-key Algorithm works by taking the message and combining it with a shared key that inputs the algorithm then outputs a ciphered message. Two ways of symmetric-key algorithm encryption involve block ciphers and stream ciphers. Stream cipher is a symmetric key cipher where plaintext digits are combined with a pseudorandom cipher digit stream (keystream). In astream cipher each plaintext digit is encrypted one at a time with the corresponding

Discuss how these concepts relate to marketing practices. Answer: Human needs are states of felt deprivation. Needs are part of the human make-up; they are not created by external forces. Humans have a basic physical need for food, clothing, warmth, and safety; a basic social need for belonging and affection; and a basic individual need for knowledge and self-expression. Unlike needs, wants are not innate; instead, wants are needs shaped by culture, society, and individual personality. For example, an American needs food but wants a Big Mac and a soft drink. An American with ten dollars needs food, wants a Big Mac and soft drink, and demands lunch at McDonalds. Wants become demands when they are backed by consumers’ buying power. Marketers conduct extensive research to understand customers’ wants and demands. They then attempt to fulfill customers’ wants and demands through their market offerings. Diff: 2Page Ref: 6 64) In a short essay, explain how and why marketers go beyond selling a product or service to create brand experiences. Answer: Sellers are most effective when they focus more on the benefits and experiences produced by their products and services than on the specific products and services themselves. Smart marketers focus on creating a brand experience, incorporating several products and services for their customers. By doing so, marketers hope to increase customer satisfaction, creating a body of customers who will repeatedly purchase their market offerings and recommend those offerings to friends. Diff: 2Page Ref: 7 65) Compare the selling and marketing concepts, listing the key components of each philosophy. Answer: The selling concept reflects an inside-out philosophy, while the marketing concept takes an outside-in perspective. The selling concept is typically practiced when an organization is marketing products or services that buyers do not normally think of purchasing, such as insurance or blood donation. Aggressive selling focuses on creating sales transactions rather than on building long-term relationships with customers, with the aim of selling what the company makes rather than making what the customer wants. The marketing concept, on the other hand, is based upon identifying the needs and wants of target markets and then satisfying those needs and wants better than competitors do. In contrast to the selling concept, marketing focuses on the customer, not the product, as the path to profits. Diff: 2Page Ref: 10 66) Briefly explain the societal marketing concept. Give an example of an organization that has effectively used the societal marketing concept. Answer: According to this concept, firms will succeed if they take underlying consumer needs and society’s well being into account over the long term. A pure marketing concept can damage consumers’ long-run welfare by focusing exclusively on satisfying consumers’ short-run wants. Over a long period of time, this too-narrow focus can be damaging to the company. In setting their marketing strategies, marketers today need to balance company profits, consumer wants, and society’s interests. Johnson Johnson is an example of a company that has successfully implemented the societal marketing concept. The organization stresses honesty, integrity, and putting people before profits, an ethic that helped Johnson Johnson quickly address and recover from the poisonous tampering of Tylenol capsules in 1982. Diff: 2Page Ref: 11 67) Explain why the aim of customer relationship management is to create not just customer satisfaction, but also customer delight. Answer: Customer satisfaction cannot be taken for granted. Because brand loyalty is dependent upon strong customer satisfaction, companies strive to retain, satisfy, and even delight current customers. Firms create customer delight by promising only what they can deliver and then delivering more than what they promised. They also create emotional relationships with key customers. Delighted customers make repeated purchases and become customers for life. More importantly, they also essentially become an unpaid sales force for the firm as â€Å"customer evangelists† who tell other potential customers about their positive experiences with the product. Diff: 1Page Ref: 13 68) In a short essay, discuss the challenges and advantages that new communication technologies have created for marketers. Answer: Through the Internet and related technologies, people can now interact in direct and surprisingly personal ways with large groups of others, from neighbors within a local community to people across the world. With communication technologies such as e-mail, blogs, Web sites, online communities, and online social networks, today’s marketers incorporate interactive approaches that help build targeted, two-way customer relationships. Marketers can create deeper consumer involvement and a sense of community surrounding a brand, making a brand a meaningful part of consumers’ conversations and lives. However, while new communication tools create relationship-building opportunities for marketers, they also create challenges. They give consumers a greater voice, and therefore greater power and control in the marketplace. Today’s consumers have more information about brands than ever before, and they have a wealth of platforms for airing and sharing their brand views with other consumers. This benefits companies when views of its products are positive, but can be damaging when customers share stories of negative experiences with a company’s products. Diff: 2Page Ref: 18 69) Define customer equity and explain how a company can increase it. Answer: Customer equity is the sum of the lifetime values of all a company’s current and potential customers. Customer equity is dependent upon customer loyalty from a firm’s profitable customers. Because customer equity is a reflection of a company’s future, companies must manage it carefully, viewing customers as assets that need to be maximized. To increase customer equity, companies should work to delight their customers and establish full relationships with their most profitable customers. Diff: 1Page Ref: 23 70) Explain how the Internet has transformed the way in which we do business today. Answer: The Internet links individuals and businesses of all types to each other. The Internet allows firms access to exciting new marketspaces. The Internet has spawned an entirely new breed of â€Å"click only† companies–the â€Å"dot-coms. † The post-Internet frenzy of the late 1990s has introduced companies that are both savvy and face promising futures. These companies use a set of new Web technologies to reach customers, including blogs (web logs), vlogs (video-based logs), and social networking sites. â€Å"Brick-and-mortar† companies of the past are now â€Å"click-and-mortar† companies, with online presences aimed at attracting new customers and strengthening bonds with current customers. Approximately 65% of American Internet users now shop online, making a Web presence a necessity for any organization.

Evaluation and Observation of Children †Free Samples to Students

Question: Discuss about the Evaluation and Observation of Children. Answer: Introduction Childhood care services are widely popular in the different parts of world for the innumerous benefits that it provides to the families attached to any of such child care centre. Parents and families have always remained the primary learning centre for their kids for a long time back in past. However, things are now shifting towards the modern way of nurturing, which is done by the different child care centers across the world (Ruhm and Waldfogel 2012). The main purpose of this assignment is to analyze in detail the process of childhood care services, which is now in practice in the different countries across the globe. Anecdotal records- It is focused on observing the different child actions such as body language, facial expressions, direct quotes, voice tone etc. This is important in analyzing the development, skills, interest, needs and abilities of a child. These records are very useful n evaluating the progress of an individual child. Learning stories- It is more about learning the different things through painting works. It encourages kids to be innovative and expressive with their paintings. Running records- This is a technique to check the behavioral stage of kids. This is done by allowing them to speak for 2 to 5 minutes. Based on what they have said, their behaviors are analyzed. Such analysis helps in understanding the childs behavior in depth. Sociograms- It is a diagrammatic representation of the social awareness that a child develops being there in such child care service centers. This educates the observer on the interactions and the different social behaviors of a particular child in the same group or with the others. Jottings- It covers significant events, conversations and behaviors in short details. This can be done in couple of sentences or within a paragraph if extended. Event samples- This helps in collecting a series of samples of different events. Different events can be the different situations and the related behavior of kids. Time samples- It helps in collecting the samples of children on terms that keeps on repeating throughout the day. This helps in recording a particular behavior or a series of negative behavior that are repeated in a single day. Work samples- This includes the different kinds of works assigned to an individual child. Such works can include but are not limited to such as drawings, paintings, writing and cutting. Photographs- Pictures says a lot. A series of different photos helps in observing the different expressions of a child under different circumstances. Work samples- One of such examples can be of writing content over a given topic. This will tell the level of understanding that the particular children has developed. Anecdotal records- One of such examples can be of Jack playing with the others in groups. Jack was very interactive while playing with the other group members. Jack was energetically grabbing on his opportunity and shouting louder to encourage others. One of the group members did approach Jack regarding some playing skills. Jack did laugh and had said that he is the best because he is being approached by others. Running records- One of such examples can be of saying on a topic such as what do you feel for others for five minutes. Implementing one example into childhood program Childhood assessment is a process of making a database of a child with the use of available information. This further helps in planning the educational and the behavioral needs that the particular child needs (Resources for Early Learning 2017). The example given for Running records in the above section can be helpful in deriving knowledge on social and emotional development in the target child. The topic will encourage the particular child to express his or her emotions regarding the others in group (Pellegrini, Symons and Hoch 2014). This will help in judging them on various skills such as the follows: Communication skills Socialism Level of emotions These are just few of the parameters; however, there can be many others. A series of such test will help in comparing the data gathered on different such events. Purpose of handling children and the needs to observe them The purpose of handling kids is to support those families who are concerned with the early development of their child. Parents and families were believed as the primary learning center for their kids in the long time back in past. However, they have largely been shifted to childhood care centers. This is for several purposes such as a systematic handling of their kids. Tools and techniques that the different childhood care centers use are more or less unknown facts to the parents. This is what justifies the purpose of handling techniques of such institutions (Ernst 2012). Observation is needed as it helps in analyzing the successive changes particular to a child. Observation is needed to check the improvement after children being incepted into a childcare home. This is required to analyze the level of works that are still needed to support the development in a child (Rusby et al. 2013). Information collected through two most important techniques such as Anecdotal and Running records helps in analyzing a child with the help of different aspects such as communication and behavioral aspects. Such analysis tells the interest of a particular child. Moreover, this also helps in analyzing the individuals ability, which is useful in further implementing the information on future learning. Additionally, these approaches are also important in analyzing the further development that an individual need (Valerio et al. 2012). For childcare centers, it is important that they have sufficient data on the different child enrolled in the centre. This is necessary for both the attainment of their organizational objectives and also for the strengthening of the parents trust on such institutions. This kind of assessment encourages for a regular observation of kids based on performance evaluation. This can be understood from the different observation method, which has already been discussed earlier in this paper. The different observation style helps to find the different learning stages of a child. This is how formative assessment progresses in a childcare centers. The evaluation made at the end of each observation method supports the progress of summative assessment. Summative assessment is the final analysis of a performance based on the set parameters. It encourages the repairing of shortfalls that are there in a child. Such shortfalls can be analyzed with the help of different observation methods such as the Running records and the Anecdotal records. This is criteria specific that encourages the progress done with the help of separate parameters set for different children in a childhood care center. The different criteria are analyzed with the help of the results derived from the different observation approaches discussed above. This is done to analyze the summative data, which are derived from the different observation approaches. The results of different observational approaches for a particular child help to progress the assessment done through Ipsative. The different results are compared with each other to understand the progress of assessment. Understanding the importance of assessment for parents and families- The different assessment approaches that are conducted in the childcare centers are very important for the parents and the families. They will get to know the successive progress in their children. Such information will also help them in assisting their kids when the kids will be with their parents. They will then be able to analyze their kids based on different such parameters that were not known to them earlier. Such assessments will make them understand the areas to work for and to help their child overcome the identified issues. Such assessments will also assure the parents about the particular childcare center. They will have an enlarged faith on the services offered by their chosen childcare service provider. Moreover, this will act as an advertising stunt for the respective childcare center (Perrin et al. 2014). Defining the observation and explaining its needs- Observation can be defined as a process that helps to analyze the performance of an individual. This is highly required in a childcare center due to the purpose such centers serve. Observation will help to gather information of every single child in the childcare center. This is indeed required to effectively work with each child member in a childhood care center (Hamre et al. 2012). Observation helps to conduct a close monitor of each child member of a childcare center. Such close monitoring is indeed required to justify the importance of childhood care centers. Such close monitoring will help the childcare centers with the necessary data of the different child member. This is extremely required to understand the capability of each child member. This is also required to understand the needs supports that a particular child needs. This is also important to strengthen the trust of parents on childcare service providing centers (Denham et al. 2012). Ways to involve parents in the observation process Following are the ways that can help to involve parents in the observation process (): Through informal conversations in relation to the child Both parents professionals are needed to bring the issues they both have identified in the open Professionals are needed to connect with the parents by letting them aware with the proceedings Parents should be asked to critically analyze the proceedings of the respective childcare center Such circumstances might cause deviation from the set objectives. If a childcare center does not have observation and evaluation process then it will lack in analyzing the progress of children. This will also fail in supplying sufficient data to the parents, which could hamper their trust on such institutions (Dewey 2013). Conclusion Childcare centers are playing an important role in delivering the commitments they have made to the parents families across the globe. However, such centers should follow the fundamentals of institution that includes but are not limited to such as observation and evaluation of progress of an individual child. Moreover, observation and evaluation are also important for strengthening the relationship with the parents and their faiths on such centers. Observation and evaluation are essential to the success of purpose and objectives of different childcare centers across the globe. Moreover, this is also essential for an incrementing benefit of such institutions.

Analysis of Wants by Grace Paley

Analysis of 'Wants' by Grace Paley Wants by American writer Grace Paley (1922 - 2007) is the opening story from the authors 1974 collection, Enormous Changes at the Last Minute. It later appeared in her 1994 The Collected Stories, and it has been widely anthologized. At about 800 words, the story could be considered a work of flash fiction. You can read it for free at Biblioklept. Plot Sitting on the steps of the neighborhood library, the narrator sees her ex-husband. He follows her into the library, where she returns two Edith Wharton books she has had for eighteen years and pays the fine. As the ex-spouses discuss their different perspectives on their marriage and its failure, the narrator checks out the same two novels she has just returned. The ex-husband announces that he will probably buy a sailboat.  He tells her, I always wanted a sailboat. [†¦] But you didnt want anything. After they separate, his remark bothers her more and more. She reflects that she doesnt want things, like a sailboat, but she does want to be a particular kind of person and to have particular kinds of relationships. At the end of the story, she returns the two books to the library. Passage of Time As the narrator returns the long-overdue library books, she marvels that she doesnt understand how time passes. Her ex-husband complains that she never invited the Bertrams to dinner, and in her response to him, her sense of time collapses completely. Paley writes: Thats possible, I said. But really, if you remember: first, my father was sick that Friday, then the children were born, then I had those Tuesday-night meetings, then the war began. We didnt seem to know them anymore. Her perspective starts at the level of a single day and one small social engagement, but it quickly sweeps out to a period of years and momentous events like the births of her children and the commencement of war. When she frames it this way, keeping library books for eighteen years seems like the blink of an eye. The Wants in Wants The ex-husband gloats that he is finally getting the sailboat he always wanted, and he complains that the narrator didnt want anything. He tells her, [A]s for you, its too late. Youll always want nothing. The sting of this comment only increases after the ex-husband has left and the narrator is left to ponder it. But what she realizes is that she does want something, but the things she wants look nothing like sailboats. She says: I want, for instance, to be a different person. I want to be the woman who brings these two books back in two weeks. I want to be the effective citizen who changes the school system and addresses the Board of Estimate on the troubles of this dear urban center.  [†¦] I wanted to have been married forever to one person, my ex-husband or my present one. What she wants is largely intangible, and much of it is unattainable. But while it may be comical to wish to be a different person, there is still hope that she can develop some attributes of the different person she wishes to be. The Down Payment Once the narrator has paid her fine, she immediately regains the goodwill of the librarian. She is forgiven her past faults in exactly the same measure that her ex-husband refuses to forgive her. In short, the librarian accepts her as a different person. The narrator could, if she wanted, repeat the exact same mistake of keeping the exact same books for another eighteen years. After all, she doesnt understand how time passes. When she checks out the identical books, she appears to be repeating all her same patterns. But its also possible that shes giving herself a second chance to get things right. She may have been on her way to being a different person long before her ex-husbands issued his scathing assessment of her. She notes that this morning - the same morning she took the books back to the library - she saw that the little sycamores the city had dreamily planted a couple of years before the kids were born had come that day to the prime of their lives. She saw time passing; she decided to do something different. Returning library books is, of course, mostly symbolic. Its a bit easier than, for instance, becoming an effective citizen. But just as the ex-husband has put a down payment on the sailboat - the thing he wants - the narrators returning the library books is a down payment on becoming the sort of person she wants to be.

Strategies for Acing a Multiple Choice Test

Strategies for Acing a Multiple Choice Test We all have to study and take a multiple choice test at some point in our lives. Since these tests are so prevalent, its important to have a few strategies under our belts when we sit for the exams. Read below, because these multiple choice test tips are sure to help you get the score you need on whatever exam youre taking next. Multiple Choice Strategies Read the question while covering up the answer choices. Come up with an answer in your head, and then check to see if it’s one of the choices listed. Use a process of elimination to get rid of as many wrong choices as you can before answering a question. Wrong answers are often easier to find. Look for extremes like never only or â€Å"always. Look for opposites like a substitution of –1 for 1. Look for similarities like conjunctive for subjunctive. Those could be distractors.Physically cross off wrong answer choices so you are not tempted to go back at the end of the test and change your answer. Why? You will read more about trusting your gut in a minute.Read ALL the choices. The right answer may be the one you keep skipping. Many students, in an attempt to move quickly through the test, tend to skim answer choices instead of reading them thoroughly. Do not make that mistake!Cross off any answer that does not fit grammatically with the question on your multiple choice test. If the test blank is looking for a singular noun, for instance, then any question choice displaying a plural noun will be incorrect. If you struggle t o figure it out, then plug the answer choices into the problem to see if it works.   Take an educated guess if there is no guessing penalty like there used to be on the SAT. You will always get the answer wrong by skipping it. You at least have a shot if you answer the question.Look for wordy answers. Unless you’re taking a standardized test, the correct answer is often the choice with the most information. Teachers often have to put as much info down as possible to make sure the answer choice can’t be disputed.Remember that you’re looking for the best answer. Often, more than one answer choice will be technically correct on a  multiple choice test. So, you have to choose which one fits best  with the stem and in the context of the reading passage or test.Use your test booklet or scratch paper. It often helps to write as your work, so write down formulas and equations, solve math problems, outline, paraphrase and underline to help you read. Use the scratch paper to help you work things out logically.Pace yourself. If you get stuck on a questi on, circle it and move on. Come back at the end of the test so you don’t waste precious time on something you may not get right anyway. Trust your gut. Definitely go back through your test to make sure you’ve answered everything, but keep your answers the same unless you’ve discovered new information in a later part of the test to disprove your answer.

The Real Meaning of the Type of Animal Caregiving Research Paper

The Real Meaning of the Type of Animal Caregiving - Research Paper Example Animal rights advocates have been campaigning for the proper treatment and care of every being other than man. One of the most popular advocacies is the crusade against the use of fur as a wardrobe that well-known fashion models have been supporting. It is also known all over that dog-fighting is highly discouraged. There are a lot of animal rights to enumerate. But as people become aware of the animals’ privileges are they also conscious of proper veterinary care for these beings? Veterinary care is sort of mind, not just the animals’ welfare, but their health in particular. Understanding the term and its etymology will help us understand the real meaning of this type of animal caregiving. Merriam-Webster Online Dictionary (â€Å"Veterinary†) states that the term veterinary derives from a Latin word veterinarians that pertains to beasts of burden. It is similar to the Latin veter- and fetus that is related to the practice or the knowledge in â€Å"prevention, c ure, or alleviation of disease and injury in animals, especially domestic animals.† The people who practice such skill and knowledge are called veterinarians. They also carry the title of â€Å"doctor.† But veterinarians are often regarded with lesser professional esteem compared to the physicians of human beings. Hence, few have developed an interest in this field. But why is veterinary care important? Apart from rabies, there are already a number of deadly animal diseases known to the world, one of which is avian influenza. These diseases can also be fatal when transmitted to humans.

A rhetorical analysis of an argumentative article of your choosing Essay

A rhetorical analysis of an argumentative article of your choosing - Essay Example The article on gun laws was viewed almost by everyone in the world and especially the United States citizens. This was as a result of the Colorado cinema shooting fiasco. The authors’ argument is generally based on the perfect implementation of gun laws in the United States and the rest of the word. This finally will enhance the respect of the sanctity of human life. This paper tries to bring out an argumentative nature of the gun law article. This was because of various opinions from different individuals after the Colorado cinema shooting. According to these composed writers, in 2007, a total number of twelve thousand six hundred and thirty two people in the United States succumbed to firearms related injuries. Another 48676 were admitted to hospitals for gunshot wounds (Bellesiles 28). These two writers are of the opinion that; the restriction gun laws or even relaxing them will reduce the death toll thru shooting which has been a contentious issue in America. These intelle cts on law furthermore argue that proponents of tighter gun laws will definitely do away with these vital and risky weapons falling on wrong hands. These wrong hands in their argumentative article may include criminals, addicted drug users or even the mentally ill individuals (Carter 180). The two with no doubt believe that drug users are majorly the result of the senseless shooting in the public social settings. The gun laws article also criticises the age individuals should be allowed to acquire guns. In the United States, the bare minimum age to hold a gun legally is eighteen years old. This to some extent is not appropriate for these young individuals are not mature for an efficient and effective decision-making (Ramage 98). This according to these two researchers cum writers, in most cases, has also resulted into premature exchange of words and shooting senselessly by the young individuals in the United States. These two writers also believe it is not only in the United States where gun laws are very weak, but this extends to several parts of the world. In a country like South Korea, these prolific writers believe and thus argue that homicide cases related to guns are far less compared to the United States due to strict gun laws which they as well understand is the father of democracy. These examples of fundamentally different states in thefield of gun laws prove that restricting gun laws will actually benefit the populace. These writers, on the other hand, argue that restricting gun laws is more beneficial. Through the restriction of gun laws, the articles firmly believe and argues that day-to-day senseless shooting is curbed totally. Private gun dealers who sell guns ignore critical regulation to those who purchase the guns hence about 85percent of all guns used in crimes unrecovered by law enforcers are linked to them. All these private party sales allow almost everybody to put a stockpile of weapons (Spitzer 238). This as well greatly undermines the g overnment efforts to control the illegal firearms in the country. A private party gun sale is completely unwarranted. This makes the private party gun sales comparable to over the counter purchase of home effects. There are those who argue and believe that relaxing gun laws would create a safer state. Gun advocates and gun manufacturers strongly argue that more guns equals’ tighter security as every gun holder can act as a police. An example is where a criminal or terrorist who pulls out an assault automatic rifle to start

The reassessment of security issues and their impacts on Adventure Essay

The reassessment of security issues and their impacts on Adventure Works business processes - Essay Example In order to promote business on the web requires certain security measures and a fail / safe network environment. After reviewing, the factors that may disrupt organization services are identified below: No Security Policy Defined No Protection of critical Assets on the network No proper data backup policy Moreover, some critical issues or weaknesses that may influence an organization’s business operations need to be addressed on an urgent basis. The top rated issues are: {Security Issue No 1}: No data backup policy defined {Security Issue No 2}: No Disaster recovery plan defined {Security Issue No 3}: No Support for Server requiring 100% uptime {Security Issue No 4}: No IP surveillance for critical server {Security Issue No 5}: In sufficient security for LAN It is vital for Adventure Works to overcome these issues as soon as possible, as these vulnerabilities will directly affect the business operations of the organization. Creating Security Policy As there is no security pol icy defined currently for Adventure Works, the new security policy will illustrate the implementation procedures of security controls that are identified by analyzing the current network and business practices. {Security Issue No 1}: As the organization is maintaining Entity Resource Planning and Customer Relationship Management Server that are considered as core servers may face loss of data or server crash that may result in halting the services. Adventure Works is dependent on these servers, as these servers process most of the paperless work, creating a backup on a regular basis is essential. Recommendation: In order to incorporate a mirror of these servers, disk-mirroring techniques using RAID is recommended. As RAID will synchronize the data on two servers simultaneously, if any one of the server stops responding, the other service will be triggered to ‘primary operation’ mode. {Security Issue No 2}: As one of the branches of Adventure Works is in Mexico, there is a possibility of an earthquake. The impact of earthquake may create disrupt the overall operation of an organization’s network, as well as loss of data. Recommendation: Relocating the instance of critical server data on a different location may be a better choice. In that case, if an earthquake affects Adventure Works network seriously, the data can be extracted from the second location. {Security Issue No 3}: As the core servers of Adventure Works are CRM and ERP, there is a requirement of making their availability 24/7. Moreover, an alternate connectivity is also required that may make them operational if the primary network access is not available due to some issues in a switch. Recommendation: in order to ensure stable power supply, a Power over Ethernet technology is recommended. A comprehensive definition is available in network dictionary, which states as â€Å"Power over Ethernet (PoE) technology describes any system to transmit electrical power, along with data, to remote devices over standard twisted-pair cables in an Ethernet network. This technology is useful for powering IP telephones, wireless LAN access points, webcams, Ethernet hubs, computers, and other appliances where it would be inconvenient or infeasible to supply power separately.† Moreover, the network engineer can rout a dedicated alternate network connection for making the server operational. {Security Issue

Applications of Semiconductor lasers

Applications of Semiconductor lasers Abstract- Semiconductor lasers have the potential to meet the demands of next generation high speed optical network applications and also have great impact on various other technology domains. Its low cost, easy wavelength tune ability, low power consumption and pure output make it ideal for optical communication applications. This paper is a review of the merits, demerits, current applications, commercial availability and future directions of semiconductor lasers in optical communication. Comparative analysis of these semiconductor lasers with respect to various parameters also been conducted. Keywords: Semiconductor lasers, Fabry-Perot laser, Distributed feedback (DFB) laser, External Cavity Diode Lasers (ECDL), Multi Quantum Well (MQW) laser, Vertical Cavity Surface Emitting Lasers (VCSEL) i.Introduction The semiconductor lasers were discovered in 1962 by Robert Hall and his team members [1, 2]. With the advent of this technology patents and articles started to publish on this technology but at that time this technology was not mature enough to realize the dreams of the scientists, engineers and physicist. But with advancement in the field and the enabling technologies soon made it possible to produce inexpensive commercially available semiconductor laser. The invention of semiconductor lasers not only revolutionizes the optical communication but it has many applications in other domains also. Semiconductor lasers are one of the popular optical communication light source for data transmission. They are supposed to be the laser of the future, because of their compactness in size, easy integration, more output power, optical pumps for solid-state lasers (primary light source i.e laser diode pumps another solid state lasers) and their rapid improvement. Semiconductor lasers are essentially diodes which produces coherent light through the process of stimulated emission. They uses semiconductor as a gain medium. The gain medium is pumped by an external source, which is electrical in nature in case of semiconductor lasers [3]. As they are basically p-n junctions, so they are compact and can be fabricated on large scale by the use of advance semiconductor IC technology. Semiconductor lasers are very efficient in converting electrical power into optical power [10]. In section.II basic types of semiconductor lasers are described in terms of their basic working procedure, advantages, disadvantages, commercial availability future directions and applications. Section.III produces the comparison of semiconductor lasers with respect to various parameters and section.IV contains the conclusion. II. Types of semiconductor lasers Following are the basic types of semiconductor lasers Fabry Perot (FP) Lasers Distributed Feedback (DFB) lasers Multi Quantum Well (MQW) laser External Cavity Diode Lasers (ECDL) Vertical Cavity Surface Emitting Lasers (VCSEL) A. Fabry-Perot (FP) lasers In FP lasers, mirrors create the right condition for the lasing to occur. Resonate cavity is formed when two mirrors are put in front of each other. The bouncing of light will take place between these two mirrors, the distance between these two mirrors are adjusted in such a way that this distance is the integral multiple of half wavelength, only is such scenario light will reinforce itself. Wavelengths that are not resonant they undergo destructive interference and deflect. One of the two mirrors is fully reflective and the second mirror allows very small amount of light to pass through [4]. Figure.1.a: Fabry Perot Laser conceptual structure, Ref: [4] Figure.1.b: Fabry Perot Laser structure, Ref: www.scholar.lib.vt.edu A.1. Advantages FP laser gives comb of (Amplified Spontaneous Emission) ASE peak uniform in frequency [5]. FP laser can be used for transmission of data with multimode optical fiber [6]. FP laser also have uniform intensity over Erbium Doped Fiber Amplifier (EDFA) [5]. Perfect for optical links where long term power and wavelength stability is required. A.2. Disadvantages High dispersion in high speed and long transmission system because the spectral width can span as much as 5 nm [6]. At 2.5Gbps and higher the wavelength center of FP laser goes out of wavelength tolerance. Not suitable for long distances. With the improvement in VCSELs technology, applications of 1310 nm and 1550 nm applications are moving from FP laser to VCSEL. A.3. Future directions and Applications Increase in bandwidth up to 15 GHz (the running value) by reducing low frequency roll off parasitic effects of bias circuits by injection locking [7]. FP lasers can generate single longitudinal mode laser [8]. FP lasers external optical modulator for optical access network [9]. Spectral width of FP laser allows transmission to distances of 40 Km at 1.7 Gbps.[5] FP offers Corse wavelength division multiplexing (CWDM) with channels at 1.3ÃŽÂ ¼m and 1.5ÃŽÂ ¼m simultaneously on a single fiber [5]. FP lasers offer benefits in LAN that use one wavelength per fiber [6]. FP laser can be used as multi wavelength source of Amplified Spontaneous Emission (ASE) for spectrum sliced [5]. The 1550 nm FP laser can support Synchronous Optical Network (SONET) [6]. A.4. Commercial availability of FP lasers Multiple Application Platform (MAP) FP laser [9] is FP laser source with key features like single mode or multi mode output, internal modulation, LAN extensions for instrumentation (LXI) compliant etc. This device has weight of almost of half kilo gram is capable of operating on different optical fibers such as Flexcorà ¢Ã¢â‚¬Å¾Ã‚ ¢ and SMF-28 [10] with operational temperature range of 10à ¢Ã‚ Ã‚ °C to 40à ¢Ã‚ Ã‚ °C. This product is commercially available. B. Distributed feedback (DFB) lasers In FP laser there is feedback of light from the mirrors, this light feedback can be provided in distributed manner by series of closely spaced mirrors/reflectors (means there is a periodic variation in the width of the cavity). There is a corrugated section in the cavity; the incident light passes through section causes series of reflections. If the corrugation period is the integral multiple of half wavelength (Bragg condition) the resulting transmitted wave will add in phase. This mechanism suppresses other longitudinal modes and allow only single longitudinal mode whose wavelength is equal to twice the corrugation period. [11] Figure.2. DFB laser structure [4] B.1. Advantages DFB lasers provides better wavelength stability than cleaved end face laser [12] The line width of DFB is less than that of reflective end face lasers [12]. Low chirp [13] Better wavelength selectivity. DFB laser is used in high performance system because of its narrow spectral output width [6]. B.2. Disadvantages The amplitude of the standing wave is fixed because of gratings Emitted wavelength near threshold current cant be controlled [14] Wavelength chirp is associated with the spatial burning of the carrier holes. Some values of rare facet phase give unacceptable performance. B.3.Future directions and applications of Distributed feedback (DFB) lasers All optical flip-flop is one of the building block for fast optical packet switching as it temporary stores the header information while the payload is routed to the correct output port. Single distributed feedback (DFB) laser diode based, all optical flip flop can be used to serve this purpose. Experimental results shows that DFB lasers can provide optical memory in an economical way and at the same time shows fast switching of optical packets (as low as 45 ps can be achieved). Using DFB lasers as an all optical flip flop 40 Gbps can be switched. [15] Used in DWDM system where tune ability of signals are required. Used in the sensing of extreme narrow line width of the signal. B.4. Commercial availability of Distributed Feedback laser The production of Quantum dot pure Green laser [16] is possible by using DFB laser technology. DFB laser gives high reliability for optical communication to form quantum dot crystal with a wavelength of 1064nm [16]. There is significant amount of reduction in power consumption for converting 1064nm quantum dot laser from electricity to light by the use of DFB laser. C. Multi Quantum well (MQW) lasers In Quantum well lasers the active region is very narrow which causes quantum confinement to occur. The wavelength which emits is dependent on the width of the active region rather than the band gap. This feature gives shorter wavelength than conventional lasers [17]. Figure.3. Cavity structure of MQW laser [4] C.1. Advantages Enhanced gain due to quantum well structure and gain co-efficient is usually 3 times or more than single layer FP laser [13] Produce shorter oscillation wavelength Smaller linewidth enhancement factor (ÃŽÂ ±), at larger linewidth enhancement factor the laser instability is enhanced [13]. Small optical losses Better confinement of laser actions because of multiple active regions. Low threshold current High modulation speed Low temperature dependency C.2. Disadvantages The internal structure of MQW laser is designed such that it is more susceptible to back reflections. C.3. Future directions and Applications Modulating retro reflector combines optical retro reflector and optical modulator (MQW lasers). Strained quantum well technology can become the core technology for high performance semiconductor device by expanding the flexibility of band engineering [18]. Optical repeaters, as it gives saturated output power to about 3dBm. C.4.Commercial availability of MQW lasers SANYO GaAlAs index guided laser diodes with MQW structure, these are infrared powerful lasers source [19] of maximum power up to 200mW and wavelength range of 782nm to 830nm is commercially available. SONY GaAlAs index guided laser diodes with MQW structure; these are infrared powerful lasers source [19] gives optical power range from 90mW up to 60W. This huge optical output power gives high brightness. D. External Cavity Diode Lasers (ECDL) ECDL can also be used to achieve the single longitudinal mode wavelength. ECDL is a semiconductor based laser with one end of the laser diode has anti reflective coating and laser resonator is completed with collimating mirror and external mirror. As they are tunable lasers so for wavelength selection they use diffraction gratings. End mirror contains collimating lens and diffraction grating. The anti reflective coated end of the diode gets feedback from the diffracted beam. Tuning of the emitted wavelength is done through the rotation of the diffracting grating. There is some more variation for this setup. [11, 20] Figure.4. EDCL setup Ref: www.clu-in.org D.1.Advantages Side mode suppression ratio (SMSR) is better than -40 dB and has narrow intrinsic line width Pulse repetition rate can easily be selected [21] Filter can be inserted for the fixing of emission wavelength in mode locked diode laser [21] etc. D.2. Disadvantages The direction of output beam changes by rotating the diffraction grating which not suitable for many optical communication applications. In fixed direction of the output beam, the zero order reflection of the beam bounced by the mirror is lost. D.3.Future directions and applications Tunable continuous wave THz radiation can be generated by the use of dual mode ECDL from 250 MHz to several THz [22] Without mode hopping wavelength tuning over 40 nm around 1550 nm is expected by new configuration of EDCL with all dielectric thin film Fabry Perot filters. [23] Atomic clock: ECDL is used in the optical system of the atomic clock; it is used for the cooling and the detection of clock transition. [24] Mode locked ECDL are mostly used in optical communication (DWDM) for data transmission. [21] Testing and measurement in optical fiber communication Non-linear frequency conversion. D.4. Commercial availability of ECDL TEC-100 and TEC-120 [25] External cavity diode Littrow laser system gives optical output power up to 200mW and running range (mod-hop free) up to 30GHz. DLX-100 [26] External cavity tunable diode gives output power up to 1W and mod-hop free tuning up to 15GHz. E. Vertical Cavity Surface Emitting Lasers (VCSEL) VCSEL achieves single longitudinal mode operation in different manner. The active region is placed between two highly reflective surfaces/mirrors. These two reflective surfaces have alternated high and low refractive index. The reflectivity of the surfaces is between 99.5-99.9% that is why light oscillates perpendicularly through the layers and emits from the top or the bottom of the device. [27] E.1. Advantages It has high wavelength stability It is less sensitive to temperature (can operate reliably up to 80 à ¢Ã‚ Ã‚ °C) Less refrigeration is required for VCSEL as it operation do not emit much heat. It provides high powered per unit area ( up to 1200W/cm2) It emits circular beam as a transmitter which leads to small optical loss. Figure.5. VCSEL structure [4] E.2. Disadvantages Because of high mirror reflectivity in the VCSEL internal structure lowers the optical output power. They emit low output power (in mW) because of their small active medium volume. InP based VCSEL suffers from having low conduction band offset, low conduction band offset means low confinements of electron which results improper temperature stability of active material gain. To produce longer wavelength in VCSEL, mechanism of double fusion is used. This mechanism increases the cost as it is complicated procedure [28]. E.2. Future directions and applications of Vertical External Cavity Surface-Emitting Laser (VECSEL) [20, 32] There is an issue of optical power supply for Si-photonics transceiver which are being developed for high density optical interconnect on parallel processors can ideally solved by VECSEL as the emits in 1330 nm and 1550 nm. [29] High speed modulation up to 25 Gb/sec can be achieved by using VCSEL at low current of 7.4 KA/cm2. [30] Fast modulation frequency (in GHz) made its use in optical fiber communication as transmitter Ideal for local and metro area networks as they produce low output power. Threshold less laser [31] etcà ¢Ã¢â€š ¬Ã‚ ¦ E.3. Commercial availability of (VCSEL) VCSEL technology has flourished and gives wide range of products with ultra low noise, narrow line width, high optical output power (up to 1kW) and high speed modulation (speed >5GHz) [27]. For high optical output power up to 1KW, a module for cooling of this system is used and fiber is pigtailed for high brightness VCSEL array. VCSELs are commercially available in blue, green and UV lasers [27]. iii. Comparison of semiconductor lasers In this section DFB, ECDL, MQW and VCSEL are compared with respect to different parameters and their suitability as optical transmitter in different optical networks. Parameters Tuning agent Output power ( in dBm) Tuning speed Modulation speed Lasers DFB Temperature 13 Slow (m-sec) Fast (multi-GHz) MQW Quantum confined stark effect ~7 Fast( Fast(multi-GHz) VCSEL MEMs Optically pumped 6 Electrically pumped -3 Fast(ÃŽÂ ¼-sec) Fast ( few GHz) ECDL Peizo transducer ~13 Slow(m-sec) Slow ( Table.1: Comparison of semiconductor lasers Table.1 shows relative analysis of semiconductor lasers. Each semiconductor laser has got competitive advantage with respect to different parameter. Table.2 gives a comprehensive view of the semiconductor lasers and their application in a specific network type as an optical transmitter. Semiconductor Laser Network type FP laser Short to medium range (Local Metro) Networks DFB Laser Long haul network MWQ Laser Short to medium range (Local Metro) Networks ECDL Long haul network VCSEL Short to medium range (Local Metro) Networks Table.2: Semiconductor lasers with their network type support Lasers Max spectral output width FP 5 nm VCSEL 0.5 nm DFB 0.1 nm Table.3: Spectral width comparison of short range lasers Spectral output width measure the range of the wavelengths produce by a laser. From table.3 it is evident that DFB laser has the narrowest spectral output width, which makes DFB laser the best choice for high performance short range optical transmission systems. iv. Conclusion This paper gives a review on the semiconductor lasers, their working, applications, commercial availability and future directions. Relative analysis of these lasers shows that they have competitive advantage in one or other laser parameters and this analysis also shows that which semiconductor laser is appropriate to which type of optical network. Semiconductor lasers have wide applications in optical fiber communication. Lots of exciting research is going on in this field and there is still room of improvements.

Gambling and the Brain Essay -- Biology Essays Research Papers

Gambling and the Brain Why do gamblers bet more after they just lost a hand? Why do investors throw good money after bad? Why do people believe that a string of losses makes a win more likely? Why do so many people say that they will win their money back in the next hand? Is part of the appeal of gambling its unpredictability? Or do we just look at it as a way to "get rich quick"? The answer to these questions may lie in the science of the brain. Some studies indicate that gamblers bet more after a loss because they are induced to fix an error. Their brains are telling them they've made a mistake and that they need to correct it (1). These studies could possibly explain other risky acts. If you ask many people why gamble, their response is "it is like a drug" (5). Compulsive gambling is a behavior which may rely on brain circuits that evolved to help animals assess rewards important to their survival. Researchers have found that those same circuits are used by the human brain to assess social rewards. They found that the brain systems that detect and evaluate such rewards generally operate outside of conscious awareness. The study said that much of what happens in the brain goes outside of conscious awareness. There are automatic brain circuits which affect activities such as gambling (2). However, this challenges prior notions which say that people make conscious choices about their everyday decision making. If people can get themselves to work unconsciously, how does the brain really know what it must pay conscious attention to? Also, how did evolution create a brain which makes such distinctions? Experiments performed on animals and humans are showing that the brain has evolved to shape itself according to what it e... ...times.com/ 3)Gambling has drug-like effect on brain,USA Today Newspaper article http://www.usatoday.com/news/health/2001-05-24-gambling.htm 4)Gambling—Like Food and Drugs—Produces Feelings of Reward in the Brain , Scientific American http://www.sciam.com/missing.cfm 5)You Bet Gambling Is Addictive , Business Week Online http://www.businessweek.com/bwdaily/dnflash/may2001/nf20010531_176.htm 6)The Good, the Bad, and the Anterior Cingulate, Science Journal, Science Magazine http://www.sciencemag.org/cgi/content/full/295/5563/2193a?maxtoshow=&HITS=10&hits=10&RESULTFORMAT=&fulltext=Gambling&searchid=1017881463081_295&stored_search=&FIRSTINDEX=0&fdate=3/1/2002&tdate=3/31/2002 7)The Medial Frontal Cortex and the Rapid Processing of Monetary Gains and Losses, Science Journal, Science Magazine http://www.sciencemag.org/cgi/content/full/295/5563/2279
